Edited by Josh Baker, who worked with Paul Levitz on 75 Years of DC Comics, the 720-page hardcover spotlights not only Marvel’s most famous characters, but also many of the writers and artists who gave them life — focusing largely on the creators from the 1960s’ “Marvel Age of Comics,” like Stan Lee, Jack Kirby, Steve Ditko, Don Heck, Jim Steranko, Marie Severin, John Romita, John Buscema and Gene Colan.
